TPS62822DLCT General Description

Texas Instruments' TPS62822DLCT is a top-of-the-line synchronous step-down DC/DC converter that offers a fixed output voltage of 1.8V, making it an exceptional choice for battery-powered applications. With its wide input voltage range and a peak efficiency of 93%, this device demonstrates remarkable power management capabilities. Its low quiescent current and power-save mode operation help to maximize energy efficiency and prolong battery life, while its compact 5-pin SC70 package ensures suitability for space-constrained designs. Additionally, the TPS62822DLCT comes equipped with overcurrent protection, thermal shutdown, and undervoltage lockout features, further solidifying its reliability and safety in power management applications. Its ability to deliver 2A of continuous output current establishes its versatility and robustness for a diverse array of power supply needs
